Silicone is a material made from alternate chains of silicon (a natural element) and oxygen atoms. It can come in many forms including rubber, resin and oil — those different forms make it great for everything from medical applications to insulation. Its liquid form is especially effective when used as the main ingredient in personal lubricants.

What makes silicone-based lubes so great? For one, they have a very unique, silky feel that is soothing to the skin and leaves it feeling soft and smooth. Silicone is also non-allergenic, so it’s a great choice for lube users with sensitive skin or allergies. And since these lubes contain mostly silicone instead of water, they often last longer and need to be reapplied less often.

Like water based lubes, silicone lubricants are also latex safe and generally toy safe, though you shouldn’t use them in conjunction with silicone toys as they can break down the rubber over time.

If you are using a silicone-covered toy for alone-time or with a partner then use a water-based lubricant to maintain the chemical integrity of the toy.

The best thing about silicone based lubes? They’re great for water play. Unlike water based lubes that would be quickly washed away in the shower or tub, silicone lubricants (especially when in gel form) stay put and keep friction at bay while you enjoy some slippery, wet fun.
